摘 要:Mitochondrial genome(mitogenome) can provide information for genomic structure as well as for phylogenetic analysis and evolutionary *** this study,we present the complete mitogenome of the atlas moth,Attacus atlas(Lepidoptera:Saturniidae),a well-known silk-producing and ornamental insect with the largest wing surface area of all *** mitogenome of *** is a circular molecule of 15,282 bp long,and its nucleotide composition shows heavily biased towards As and Ts,accounting for 79.30%.This genome comprises 13 protein-coding genes(PCGs),two ribosomal RNA genes(rRNAs),22 transfer RNA genes(tRNAs),and an A+T-rich *** is of note that this genome exhibits a slightly positive AT skew,which is different from the other known Saturniidae *** PCGs are initiated by ATN codons,except for COI with CGA *** six PCGs use a common stop codon of TAA or TAG,whereas the remaining seven use an incomplete termination codon T or *** tRNAs have the typical clover-leaf structure,with an exception for tRNA(AGN).The *** A+T-rich region contains non-repetitive sequences,but harbors several features common to the Bombycoidea *** phylogenetic relationships based on Maximum Likelihood method provide a well-supported outline of Saturniidae,which is in accordance with the traditional morphological classification and recent molecular works.
